Laboratory and Analytical Devices - 7.6.2 ControlFunctionStateMachineType Definition

7.6.2 ControlFunctionStateMachineType Definition

The ControlFunctionStateMachineType represents the state of a Function in a LADS Device. It uses the same StateTypes and TransitionTypes as its parent but specifies the additional Start Method to trigger state changes.

The ControlFunctionStateMachineType is formally defined in Table 89.

LADS ControlFunctionStateMachineType

Start starts a Function on the LADS Device.

7.6.2.2 Start

The Start Method starts a Function on the LADS Device.

The signature of this Method is specified below. Table 90 specifies its representation in the AddressSpace.

7.6.2.3 StartWithTargetValue

The StartWithTargetValue Method starts a Function on the LADS Device with the target value as an argument.

The signature of this Method is specified below. Table 91 and Note: The optional TargetValue can be also empty. In this case it should be handled as it not exiting.Note: The optional TargetValue can be also empty. In this case it should be handled as it not exiting.

Table 92 specify the Arguments and AddressSpace representation, respectively.

Argument	Description
TargetValue	(Optional) This value can be used to set the target value parallel with the start method.

Note: The optional TargetValue can be also empty. In this case it should be handled as it not exiting.
